Directions: Answer the question with the given information and the data. The following table gives number of t-shirts sold (in thousand units) in Delhi and Mumbai. The t-shirts are sold in different styles (S1, S2, S3 and S4) with different colours as shown in the table. Colour Delhi Style Mumbai Style S1 S2 S3 S4 S1 S2 S3 S4 Pink 61 60 69 55 65 95 66 92 Red 76 70 70 95 76 89 65 81 Green 71 89 92 65 61 70 60 72 Yellow 50 63 76 94 69 60 69 66 Blue 98 99 54 82 94 64 75 74 White 61 74 75 54 92 89 85 72 Black 90 51 76 51 86 93 94 97 The average sales of which colour of t-shirts sold is same in both the cities?

Using the formula for calculating an average, add the t-shirt sales across all four styles for each color in both cities and divide by four. For Red, the average sales in Delhi are (76 + 70 + 70 + 95) divided by 4, yielding 77.75. For Red in Mumbai, the average is (76 + 89 + 65 + 81) divided by 4, which also equals exactly 77.75. Checking the other colors reveals no matching averages between the two cities, confirming Red as the answer.
